With reference to
For example, each pixel unit includes a plurality of sub-pixels SPX. For example, each pixel unit may include a red sub-pixel, a green sub-pixel, and a blue sub-pixel, such that red, green and blue colors may be mixed to achieve color display. Alternatively, the pixel unit may include a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel, such that red, green, blue and white colors may be mixed to achieve color display. Certainly, in practical application, an emitting color of the sub-pixels in the pixel unit may be designed and determined according to an actual application environment, which is not limited herein.
With reference to
It should be noted that the display panel in the example of the present disclosure may be a liquid crystal display panel. For example, the liquid crystal display panel generally includes an upper substrate and a lower substrate that form a cell, and liquid crystal molecules encapsulated between the upper substrate and the lower substrate. When an image is displayed, there is a voltage difference between a data voltage applied to the pixel electrode of each sub-pixel SPX and a common electrode voltage applied to a common electrode, and an electric field may be formed due to the voltage difference, such that the liquid crystal molecules deflect under the action of the electric field. Due to electric fields with different intensities, deflection degrees of liquid crystal molecules are different, which leads to different transmittance of the sub-pixels SPX, such that the sub-pixels SPX may achieve brightness of different gray scales, and then achieve image display.
In the example of the present disclosure, for example, when the display panel includes red sub-pixels R11-R21, green sub-pixels G11-G21, blue sub-pixels B11-B21, red sub-pixels R12-R22, green sub-pixels G12-G22, and blue sub-pixels B12-B82, as shown in
In addition, the first group of sub-conductive parts may include a first connection strip 103 and a plurality of first electrode strips 104 arranged at intervals in the first direction Y. The first connection strip 103 extends in the first direction Y (that is, a length direction of the first connection strip 103 is the first direction Y). The first connection strip 103 may have a first face 103a and a second face 103b opposite each other in a second direction X. It should be noted that the first direction Y may intersect with the second direction X. Preferably, the first direction Y may be perpendicular to the second direction X (for example, the first direction Y may be a column direction F of the sub-pixels, and the second direction X may be a row direction X of the sub-pixels); and the plurality of first electrode strips 104 may be located at a position of the first face 103a away from the second face 103b and connected to the first face 103a. A slit is formed between two adjacent first electrode strips 104, which may be defined as a first slit S1. Ends of the two adjacent first electrode strips 104 away from the first connection strip 103 are disconnected from each other, that is, one end of the first slit S1 away from the first connection strip 103 is open, where one end of the first slit S1 away from the first connection strip 103 may be defined as an open end for convenience of description.
In addition, the second group of sub-conductive parts includes a second connection strip 105 and a plurality of second electrode strips 106 arranged at intervals in the first direction Y The second connection strip 105 extends in the first direction Y (that is, a length direction of the second connection strip 105 is the first direction Y). The second connection strip 105 may have a third face 105a and a fourth face 105b opposite each other in the second direction X. In the second direction X, the third face 105a of the second connection strip 105 may be located at one side of the fourth face 105b close to the first face 103a of the first connection strip 103. The third face 105a of the second connection strip 105 may be connected to the first electrode strip 104 close to the second group of sub-conductive parts, specifically, connected to one end of the first electrode strip 104 away from the first connection strip 103. It should be understood that the first electrode strip 104 close to the second group of sub-conductive parts refers to the first electrode strip 104 closest to the second group of sub-conductive parts in the first group of sub-conductive parts. The plurality of second electrode strips 106 are located at a position of the third face 105a of the second connection strip 105 away from the fourth face 105b and connected to the third face 105a of the second connection strip 105. A slit is formed between two adjacent second electrode strips 106, which may be defined as a second slit S2. Ends of the two adjacent second electrode strips 106 away from the second connection strip 105 are disconnected from each other, that is, one end of the second slit S2 away from the second connection strip 105 is open, where one end of the second slit S2 away from the second connection strip 105 may be defined as an open end for convenience of description.
In addition, in the pixel electrode 02, the sum of lengths of first connection strips 103 of all first groups of sub-conductive parts may be designed to be smaller than the sum of lengths of second connection strips 105 of all second groups of sub-conductive parts. It should be noted that the lengths refer to lengths in an extension direction.
In addition, the pixel electrode 02 may be connected to the transistor 01 (as shown in

It should be noted that a common electrode may be strip-shaped, and alternatively, a common electrode may be like a pixel electrode and have a plurality of common sub-electrodes, and adjacent common sub-electrodes are connected to each other by means of transverse and longitudinal bridging parts, so as to achieve common voltage transmission.
To sum up, in the example of the present disclosure, peripheries of the first slit S1 and the second slit S2 of the pixel electrode 02 are not all closed, that is, one end of the first slit S1 close to the second connection strip 105 is an open end, and one end of the second slit S2 close to the first connection strip 103 is an open end. It should be understood that when the pixel electrode 02 of the example of the present disclosure is applied to a display product, the open end of the first slit S1 and the open end of the second slit S2 may be adjacent to data lines DA (as shown in
In the example of the present disclosure, as shown in
In the example of the present disclosure, as shown in
It should be noted that, in the example of the present disclosure, only the pixel electrode having the structure is used as an example for description. In practical application, an embodiment of a common electrode may also use the structure of the pixel electrode, which is not limited herein.
The following description is based on an example in which a display panel in the example of the present disclosure is a liquid crystal display panel, and a pixel unit includes a red sub-pixel, a green sub-pixel and a blue sub-pixel, but a reader should know that colors of sub-pixels included in the liquid crystal display panel are not limited to the example.
Gray scales generally divide brightness change between darkest and brightest into several parts, so as to facilitate screen brightness control. For example, a displayed image consists of three colors: red, green and blue, each of the colors may show a different brightness level, and red, green and blue colors with different brightness levels may be combined to form different colors. For example, if a gray-scale bit quantity of the liquid crystal display panel is 6 bits, the three colors of red, green and blue have 64 (that is, 26) gray scales, and 64 gray-scale values are 0-63, respectively. If a gray-scale bit quantity of the liquid crystal display panel is 8 bits, the three colors of red, green and blue have 256 (that is, 28) gray scales, and 256 gray-scale values are 0-255, respectively. If a gray-scale bit quantity of the liquid crystal display panel is 10 bits, the three colors of red, green and blue have 1024 (that is, 210) gray scales, and 1024 gray-scale values are 0-1023, respectively. If a gray-scale bit quantity of the liquid crystal display panel is 12 bits, the three colors of red, green and blue have 4096 (that is, 212) gray scales, and 4096 gray-scale values are 0-4093, respectively.
For example, with one sub-pixel SPX as an example, when a data voltage Vda1 input to a pixel electrode of the sub-pixel SPX is greater than a common electrode voltage Vcom, liquid crystal molecules at the sub-pixel SPX may be positive, and polarity corresponding to the data voltage Vda1 in the sub-pixel SPX is positive. When a data voltage Vda2 input to a pixel electrode of the sub-pixel SPX is smaller than a common electrode voltage Vcom, liquid crystal molecules at the sub-pixel SPX may be negative, and polarity corresponding to the data voltage Vda2 in the sub-pixel SPX is negative. For example, the common electrode voltage may be 8.3 V. If a data voltage of 8.8 V-16 V is input to the pixel electrode of the sub-pixel SPX, the liquid crystal molecules at the sub-pixel SPX may be positive, and the data voltage of 8.8 V-16 V is a data voltage corresponding to positive polarity. If a data voltage of 0.6 V-7.8 V is input to the pixel electrode of the sub-pixel SPX, the liquid crystal molecules at the sub-pixel SPX may be negative, and the data voltage of 0.6 V-7.8 V is a data voltage corresponding to negative polarity. For example, with gray scales 0-255 of 8 bits as an example, if a data voltage of 16 V is input to the pixel electrode of the sub-pixel SPX, the sub-pixel SPX may use a positive data voltage to achieve brightness of a maximum gray-scale value (that is, a gray-scale value 255). If a data voltage of 0.6 V is input to the pixel electrode of the sub-pixel SPX, the sub-pixel SPX may use a negative data voltage to achieve brightness of a maximum gray-scale value (that is, a gray-scale value 255). It should be noted that there may be a voltage difference between a data voltage of a gray-scale value 0 and a common electrode voltage, for example, the common electrode voltage is 8.3 V, a positive data voltage corresponding to the gray-scale value 0 may be 8.8 V, and a negative data voltage corresponding to the gray-scale value 0 may be 7.8 V. Certainly, the data voltage of the gray-scale value 0 may be the same as the common electrode voltage. In practical application, whether there is a voltage difference may be determined according to an actual application requirement, which is not limited herein.
To further improve color cast, there is provided a drive method. The drive method may include the steps that a first display gray-scale value and a second display gray-scale value are generated according to an original gray-scale value of each sub-pixel of an image to be displayed, and in each display frame, the first display gray-scale value and the second display gray-scale value are used to control one sub-pixel in adjacent sub-pixels on a display panel to use the first display gray-scale value to display higher brightness, and control the other sub-pixel to use the second display gray-scale value to display lower brightness, respectively, where the first display gray-scale value is greater than the second display gray-scale value, such that data voltages applied to the two adjacent sub-pixels are different. For example, as shown in
An example of the present disclosure provides a drive method for a display panel. The display panel works in a plurality of continuous display frames. If current original gray-scale values corresponding to sub-pixels in the same region are the same in the plurality of continuous display frames, the original gray-scale values may be converted into two gray-scale values: a first target gray-scale value and a second target gray-scale value. The first target gray-scale value is greater than the current original gray-scale values, such that for the sub-pixels, displayed brightness corresponding to the first target gray-scale value may be higher than displayed brightness corresponding to the current original gray-scale values. In addition, the second target gray-scale value is smaller than the current original gray-scale values, such that for the sub-pixels, displayed brightness corresponding to the second target gray-scale value may be lower than displayed brightness corresponding to the current original gray-scale values. In this way, the displayed brightness corresponding to the first target gray-scale value and the displayed brightness corresponding to the second target gray-scale value are mixed, and the brightness corresponding to the current original gray-scale values is displayed. In addition, in a current display frame, a data voltage corresponding to the first target gray-scale value is controlled to be input to a first sub-pixel unit SPX-1 in a region, and a data voltage corresponding to the second target gray-scale value is controlled to be input to a second sub-pixel unit SPX-2 in the region. Moreover, in a next display frame, a data voltage corresponding to the second target gray-scale value is controlled to be input to the first sub-pixel unit SPX-1 in the region, and a data voltage corresponding to the first target gray-scale value is controlled to be input to the second sub-pixel unit SPX-2 in the region. In this way, sub-pixels having higher brightness in the current display frame may have lower display brightness in the next display frame. Sub-pixels having lower brightness in the current display frame may have higher display brightness in the next display frame. In this way, color cast may be improved by combining time color mixing with space color mixing.
As shown in
S100, when current original gray-scale values corresponding to sub-pixels in the same region are the same in a plurality of continuous display frames, the current original gray-scale values are converted into a first target gray-scale value and a second target gray-scale value.
For example, S100 may include the step that original display data of each sub-pixel in the plurality of continuous display frames is received. The original display data includes a digital voltage form of a data voltage having a corresponding gray-scale value corresponding to each sub-pixel, and the gray-scale value corresponding to the data voltage is an original gray-scale value. In this way, the current original gray-scale value of each sub-pixel in the plurality of continuous display frames may be determined according to the original display data of each sub-pixel in the plurality of continuous display frames.
In the example of the present disclosure, whether the original gray-scale values corresponding to the sub-pixels in the same region are the same may be determined according to the current original gray-scale value of each sub-pixel in the plurality of continuous display frames. If yes, it is indicated that the region displays an image of the same gray scale, such that color cast is likely to occur. For example, original gray-scale values corresponding to the sub-pixels in the region are all gray-scale values 127, such that an image displayed in the region may be a gray-scale image. For example, original gray-scale values corresponding to the sub-pixels in the region are all gray-scale values 255, such that an image displayed in the region may be a white image (for example, white clouds are displayed in the region). Therefore, in order to improve color cast, the current original gray-scale values may be converted into the first target gray-scale value and the second target gray-scale value. In addition, the first target gray-scale value is greater than the current original gray-scale values, and the second target gray-scale value is smaller than the current original gray-scale values. For example, with gray scales 0-255 as an example, if the current original gray-scale value is a gray-scale value 127, the first target gray-scale value may be set as a gray-scale value 170, and the second target gray-scale value may be set as a gray-scale value 40.
It should be noted that the region may be a whole region of an image displayed on a display panel, or may be one or more regions of partial regions of an image displayed on a display panel, which is not limited herein.
S200, in a current display frame of the plurality of continuous display frames, a data voltage corresponding to the first target gray-scale value is controlled to be input to a first sub-pixel unit SPX-1 in a region, and a data voltage corresponding to the second target gray-scale value is controlled to be input to a second sub-pixel unit SPX-2 in the region.
In the example of the present disclosure, each of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 includes at least one sub-pixel. For example, the quantity of sub-pixels included in the first sub-pixel unit SPX-1 and the quantity of sub-pixels included in the second sub-pixel unit SPX-2 may be the same. Alternatively, the quantity of sub-pixels included in the first sub-pixel unit SPX-1 and the quantity of sub-pixels included in the second sub-pixel unit SPX-2 may be different. In practical application, whether the quantity of sub-pixels included in the first sub-pixel unit and the quantity of sub-pixels included in the second sub-pixel unit are the same or not may be determined according to an actual application requirement, which is not limited herein.
In the example of the present disclosure, the at least one first sub-pixel unit SPX-1 may be adjacent to the at least one second sub-pixel unit SPX-2. For example, in a row direction X and a column direction F of sub-pixels, the sub-pixels may be repeated in sequence of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2. For example, each of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 includes one sub-pixel. As shown in
For example, with a current original gray-scale value of 127, a first target gray-scale value of 170 and a second target gray-scale value of 40 as an example, as shown in
S300, in a next display frame of the plurality of continuous display frames, a data voltage corresponding to the second target gray-scale value is controlled to be input to the first sub-pixel unit SPX-1 in the region, and a data voltage corresponding to the first target gray-scale value is controlled to be input to the second sub-pixel unit SPX-2 in the region.
For example, with a current original gray-scale value of 127, a first target gray-scale value of 170 and a second target gray-scale value of 40 as an example, as shown in
In the example of the present disclosure, a first target gray-scale value and a second target gray-scale value corresponding to sub-pixels in a first sub-pixel unit SPX-1 and a second sub-pixel unit SPX-2 in a display frame F_n+2 are basically the same as the first target gray-scale value and the second target gray-scale value corresponding to the sub-pixels in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 in the display frame F_n. A first target gray-scale value and a second target gray-scale value corresponding to sub-pixels in a first sub-pixel unit SPX-1 and a second sub-pixel unit SPX-2 in a display frame F_n+3 are basically the same as the first target gray-scale value and the second target gray-scale value corresponding to the sub-pixels in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 in the display frame F_n+1. Other display frames may be analogized in turn, which will not be repeated herein.
In the example of the present disclosure, a timing controller may convert, when the current original gray-scale values corresponding to the sub-pixels in the same region are the same in the plurality of continuous display frames, the current original gray-scale values into the first target gray-scale value and the second target gray-scale value, and output the first target gray-scale value and the second target gray-scale value to a source drive circuit. After the source drive circuit receives the first target gray-scale value and the second target gray-scale value output from the timing controller, in the current display frame of the plurality of continuous display frames, the data voltage corresponding to the first target gray-scale value may be controlled to be input to the first sub-pixel unit SPX-1 in the region, and the data voltage corresponding to the second target gray-scale value may be controlled to be input to the second sub-pixel unit SPX-2 in the region. In addition, in the next display frame of the plurality of continuous display frames, the data voltage corresponding to the second target gray-scale value may be controlled to be input to the first sub-pixel unit SPX-1 in the region, and the data voltage corresponding to the first target gray-scale value may be controlled to be input to the second sub-pixel unit SPX-2 in the region.
In the example of the present disclosure, in the plurality of continuous display frames, for a sub-pixel except the region, the timing controller may directly output a current original gray-scale value corresponding to the sub-pixel to the source drive circuit. After the source drive circuit receives the current original gray-scale value output from the timing controller, in the current display frame of the plurality of continuous display frames, the data voltage corresponding to the current original gray-scale value may be controlled to be input to the sub-pixel except the region. In addition, in the next display frame of the plurality of continuous display frames, the data voltage corresponding to the current original gray-scale value is controlled to be input to the sub-pixel except the region.
For example, the timing controller may determine whether the current original gray-scale values corresponding to the sub-pixels in the same region are within a gray-scale range in the plurality of continuous display frames in advance. If the current original gray-scale values corresponding to the sub-pixels in the same region are within the gray-scale range, the current original gray-scale values are converted into the first target gray-scale value and the second target gray-scale value, and the first target gray-scale value and the second target gray-scale value are output to the source drive circuit, such that in the current display frame, the source drive circuit may control the data voltage corresponding to the first target gray-scale value to be input to the first sub-pixel unit SPX-1 in the region, and control the data voltage corresponding to the second target gray-scale value to be input to the second sub-pixel unit SPX-2 in the region. Moreover, in the next display frame, the data voltage corresponding to the second target gray-scale value is controlled to be input to the first sub-pixel unit SPX-1 in the region, and the data voltage corresponding to the first target gray-scale value is controlled to be input to the second sub-pixel unit SPX-2 in the region. If the current original gray-scale values corresponding to the sub-pixels in the same region are not within the gray-scale range, it is difficult for human eyes to observe an afterimage, and the current original gray-scale value corresponding to the sub-pixel is directly output to the source drive circuit, such that after the source drive circuit receives the current original gray-scale value output from the timing controller, in the current display frame of the plurality of continuous display frames, the data voltage corresponding to the current original gray-scale value may be controlled to be input to the sub-pixel except the region. In addition, in the next display frame of the plurality of continuous display frames, the data voltage corresponding to the current original gray-scale value is controlled to be input to the sub-pixel in the region. Optionally, with 8 bits as an example, a gray-scale range may be gray-scale values 311-180, and includes an end value. If a gray-scale value is smaller than a gray-scale value 31 or greater than a gray-scale value 180, it is difficult for human eyes to observe and recognize mura. In this case, a drive mode of converting the current original gray-scale values into the first target gray-scale value and the second target gray-scale value may be avoided, such that power consumption may be reduced.
In the example of the present disclosure, the step that the current original gray-scale values are converted into the first target gray-scale value and the second target gray-scale value may include the step that the current original gray-scale values with a default gray-scale bit quantity are converted into the first target gray-scale value and the second target gray-scale value with a target gray-scale bit quantity. The target gray-scale bit quantity may be equal to the default gray-scale bit quantity. For example, the target gray-scale bit quantity and the default gray-scale bit quantity may both be 8 bits, 10 bits, 12 bits, etc. With 8 bits as an example, a gray-scale value 127 of 8 bits may be converted into a gray-scale value 170 and a gray-scale value 40 of 8 bits. In this case, a gray scale 170 and a gray scale 40 are mixed to form a gray scale 127. Compared with the gray scale 127, the gray scale 170 and the gray scale 40 are not sensitive to voltages, so it is not easy for a user to observe an afterimage. Alternatively, the target gray-scale bit quantity may be greater than the default gray-scale bit quantity. For example, the target gray-scale bit quantity is 10 bits, and the default gray-scale bit quantity is 8 bits. With 8 bits as an example, the gray-scale value 127 of 8 bits may be converted into a gray-scale value 680 and a gray-scale value 160 of 10 bits.
In the example of the present disclosure, the timing controller may store a first lookup table. The first lookup table may include: a plurality of different original gray-scale values corresponding to the default gray-scale bit quantity, and a plurality of first different target gray-scale values and a plurality of second different target gray-scale values corresponding to the target gray-scale bit quantity; and in the first lookup table, one original gray-scale value corresponds to one first target gray-scale value and one second target gray-scale value. For example, the original gray-scale values in the first lookup table are all gray-scale values of the default gray-scale bit quantity. For example, when a default gray-scale bit quantity is 8 bits, the first lookup table has all the gray-scale values of 0-255, and one first target gray-scale value and one second target gray-scale value corresponding to each of the gray-scale values 0-255. For example, with the target gray-scale bit quantity and the default gray-scale bit quantity of 8 bits as an example, Table 1 schematically shows first target gray-scale values L_H and second target gray-scale values L_L corresponding to gray-scale values 125-130. It should be noted that specific values of gray-scale values shown in Table 1 are only illustrative. In practical application, the specific values of the gray-scale values may be determined according to an actual application requirement which are not limited herein.
In the example of the present disclosure, the first lookup table includes first target gray-scale values and second target gray-scale values corresponding to sub-pixels with various colors. For example, the first lookup table includes a first target gray-scale value and a second target gray-scale value corresponding to a red sub-pixel corresponding to each original gray-scale value, a first target gray-scale value and a second target gray-scale value corresponding to a green sub-pixel corresponding to each original gray-scale value, and a first target gray-scale value and a second target gray-scale value corresponding to a blue sub-pixel corresponding to each original gray-scale value. For example, with the target gray-scale bit quantity and the default gray-scale bit quantity of 8 bits as an example, Table 2 schematically shows first target gray-scale values LR_H and second target gray-scale values LR_L of red sub-pixels corresponding to gray-scale values 125-130, first target gray-scale values LG_H and second target gray-scale values LG_L of green sub-pixels corresponding to the gray-scale values, and first target gray-scale values LB_H and second target gray-scale values LB_L of blue sub-pixels corresponding to the gray-scale values. It should be noted that specific values of gray-scale values shown in Table 1 are only illustrative. In practical application, the specific values of the gray-scale values may be determined according to an actual application requirement, which are not limited herein.
In the example of the present disclosure, the step that the current original gray-scale values with a default gray-scale bit quantity are converted into the first target gray-scale value and the second target gray-scale value with a target gray-scale bit quantity may include the step that the first target gray-scale value and the second target gray-scale value corresponding to the current original gray-scale values are determined from the first pre-stored lookup table according to the current original gray-scale values. For example, with reference to Table 2, when a current original gray-scale value is a gray-scale value 127, by looking up the first lookup table, it may be determined that a first target gray-scale value corresponding to a red sub-pixel is a gray-scale value 170, a first target gray-scale value corresponding to a green sub-pixel is a gray-scale value 170, a first target gray-scale value corresponding to a blue sub-pixel is a gray-scale value 170, a second target gray-scale value corresponding to a red sub-pixel is a gray-scale value 40, a second target gray-scale value corresponding to a green sub-pixel is a gray-scale value 40, and a second target gray-scale value corresponding to a blue sub-pixel is a gray-scale value 40. In this way, a data voltage corresponding to a gray-scale value 170 may be input to a red sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to a gray-scale value 170 may be input to a green sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to a gray-scale value 170 may be input to a blue sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to a gray-scale value 40 may be input to a red sub-pixel in the second sub-pixel unit SPX-2, a data voltage corresponding to a gray-scale value 40 may be input to a green sub-pixel in the second sub-pixel unit SPX-2, and a data voltage corresponding to a gray-scale value 40 may be input to a blue sub-pixel in the second sub-pixel unit SPX-2.
In the example of the present disclosure, the display panel may be driven through frame flipping, column flipping, row flipping and dot flipping. For example, with frame flipping as an example, in the display frame F_n, a data voltage input to each sub-pixel may correspond to positive polarity. In the display frame F_n+1, a data voltage input to each sub-pixel may correspond to negative polarity. In the display frame F_n+2, a data voltage input to each sub-pixel may correspond to positive polarity. In the display frame F_n+3, a data voltage input to each sub-pixel may correspond to negative polarity. However, for the first sub-pixel unit SPX-1, in the display frames F_n and F_n+2 in which the first sub-pixel unit SPX-1 displays higher brightness, polarity corresponding to the sub-pixels in the first sub-pixel unit SPX-1 is always positive. In the display frames F_n+1 and F_n+3 in which the first sub-pixel unit SPX-1 displays lower brightness, polarity corresponding to the sub-pixels in the first sub-pixel unit SPX-1 is always negative. Moreover, for the second sub-pixel unit SPX-2, in the display frames F_n and F_n+2 in which the second sub-pixel unit displays lower brightness, polarity corresponding to the sub-pixels in the second sub-pixel unit SPX-2 is always positive. In the display frames F_n+1 and F_n+3 in which the first sub-pixel unit SPX-1 displays higher brightness, polarity corresponding to the sub-pixels in the first sub-pixel unit SPX-1 is always negative. In this way, color cast may occur due to polarization of liquid crystal molecules. In order to avoid color cast due to polarization of liquid crystal molecules, in the example of the present disclosure, in the plurality of continuous display frames, polarity corresponding to the data voltage input to each sub-pixel in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 may be controlled to be reversed once after an even quantity of display frames.
For example, in the plurality of continuous display frames, polarity corresponding to the data voltage input to each sub-pixel in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 may be controlled to be reversed once after two display frames. For example, when frame flipping is used and each of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 includes one sub-pixel, as shown in
For example, in the plurality of continuous display frames, polarity corresponding to the data voltage input to each sub-pixel in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 may also be controlled to be reversed once after four display frames. For example, when frame flipping is used and each of the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 includes one sub-pixel, in the display frames F_n-F_n+3, data voltages corresponding to positive polarity are input to sub-pixels R11-B12 in a first row and sub-pixels R21-B22 in a second row, respectively. In the display frames F_n+4-F_n+7, data voltages corresponding to negative polarity are input to sub-pixels R11-B12 in a first row and sub-pixels R21-B22 in a second row, respectively. In the display frames F_n+8-F_n+11, data voltages corresponding to positive polarity are input to sub-pixels R11-B12 in a first row and sub-pixels R21-B22 in a second row, respectively. In the display frames F_n+12-F_n+15, data voltages corresponding to negative polarity are input to sub-pixels R11-B12 in a first row and sub-pixels R21-B22 in a second row, respectively. Processes of other display frames may be analogized in turn, which will not be repeated herein.
It should be noted that in the plurality of continuous display frames, polarity corresponding to the data voltage input to each sub-pixel in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2 may also be controlled to be reversed once after six, eight or more display frames, which is not limited herein.
An example of the present disclosure provides some other drive methods for a display panel, which modify embodiments in the examples. Only differences between the example and the above examples will be described below, and similarities will not be repeated herein.
In the example of the present disclosure, the timing controller may store a second lookup table. The second lookup table includes: a plurality of different original gray-scale values corresponding to the default gray-scale bit quantity, a plurality of different intermediate gray-scale values corresponding to the intermediate gray-scale bit quantity, and a plurality of first different target gray-scale values and a plurality of second different target gray-scale values corresponding to the target gray-scale bit quantity; and in the second lookup table, one original gray-scale value corresponds to one intermediate gray-scale value, and one intermediate gray-scale value corresponds to one first target gray-scale value and one second target gray-scale value. In addition, the intermediate gray-scale bit quantity of the current intermediate gray-scale value is greater than the default gray-scale bit quantity, and the intermediate gray-scale bit quantity is smaller than the target gray-scale bit quantity. For example, the default gray-scale bit quantity may be 8 bits, the intermediate gray-scale bit quantity may be 10 bits, and the target gray-scale bit quantity may be 12 bits. In this way, one gray-scale value of 8 bits may be converted into an intermediate gray-scale value of 10 bits, then the intermediate gray-scale value of 10 bits may be converted into a first target gray-scale value and a second target gray-scale value of 12 bits, and then the first target gray-scale value and second target gray-scale value of 12 bits may be used to control display brightness of the sub-pixels in the first sub-pixel unit SPX-1 and the second sub-pixel unit SPX-2, such that display brightness of the sub-pixels in the first sub-pixel unit SPX-1 is mixed with display brightness of the sub-pixels in the second sub-pixel unit SPX-2, and then brightness of a gray-scale value 127 of 8 bits is displayed. If a gray-scale value of 8 bits is directly used to conduct mixing to obtain the brightness of the gray-scale value 127 of 8 bits, mixed brightness may be rough. A gray-scale value of 12 bits is finer in brightness distinguishing, so mixed brightness of 8 bits by using a gray-scale value of 12 bits may be finer and closer to brightness of 8 bits.
For example, original gray-scale values in the second lookup table are all gray-scale values of the default gray-scale bit quantity. For example, when a default gray-scale bit quantity is 8 bits, the second lookup table has all the gray-scale values of 0-255, and one intermediate gray-scale value, one first target gray-scale value and one second target gray-scale value corresponding to each of the gray-scale values 0-255. For example, with a default gray-scale bit quantity of 8 bits, an intermediate gray-scale bit quantity of 10 bits and a target gray-scale bit quantity of 12 bits as an example, Table 3 schematically shows intermediate gray-scale values L_Z, first target gray-scale values L_H and second target gray-scale values L_L corresponding to gray-scale values 125-130. It should be noted that specific values of gray-scale values shown in Table 3 are only illustrative. In practical application, the specific values of the gray-scale values may be determined according to an actual application requirement, which are not limited herein.
In the example of the present disclosure, the second lookup table includes first target gray-scale values and second target gray-scale values corresponding to sub-pixels with various colors. For example, the second lookup table includes a first target gray-scale value and a second target gray-scale value corresponding to a red sub-pixel corresponding to each original gray-scale value, a first target gray-scale value and a second target gray-scale value corresponding to a green sub-pixel corresponding to each original gray-scale value, and a first target gray-scale value and a second target gray-scale value corresponding to a blue sub-pixel corresponding to each original gray-scale value. For example, with the default gray-scale bit quantity of 8 bits, the intermediate gray-scale bit quantity of 10 bits and the target gray-scale bit quantity of 12 bits as an example, Table 4 schematically shows intermediate gray-scale values L_Z corresponding to gray-scale values 125-130, first target gray-scale values LR_H and second target gray-scale values LR_L of red sub-pixels corresponding to the gray-scale values, first target gray-scale values LG_H and second target gray-scale values LG_L of green sub-pixels corresponding to the gray-scale values, and first target gray-scale values LB_H and second target gray-scale values LB_L of blue sub-pixels corresponding to the gray-scale values. It should be noted that specific values of gray-scale values shown in Table 4 are only illustrative. In practical application, the specific values of the gray-scale values may be determined according to an actual application requirement, which are not limited herein.
In the example of the present disclosure, the step that the current original gray-scale values with a default gray-scale bit quantity are converted into the first target gray-scale value and the second target gray-scale value with a target gray-scale bit quantity may include the step that the current intermediate gray-scale value corresponding to the current original gray-scale values is determined from the second pre-stored lookup table according to the current original gray-scale values. Then, the first target gray-scale value and the second target gray-scale value corresponding to the current intermediate gray-scale value are determined from the second lookup table according to the current intermediate gray-scale value. For example, with reference to Table 4, when the current original gray-scale value is a gray-scale value 127, the current intermediate gray-scale value may be determined to be a gray-scale value 508 by looking up the second lookup table. Then, according to the gray-scale value 508, it is determined that a first target gray-scale value corresponding to a red sub-pixel is a gray-scale value 2734, a second target gray-scale value corresponding to the red sub-pixel is a gray-scale value 641, a first target gray-scale value corresponding to a green sub-pixel is a gray-scale value 2734, a second target gray-scale value corresponding to the green sub-pixel is a gray-scale value 641, a first target gray-scale value corresponding to a blue sub-pixel is a gray-scale value 2734, and a second target gray-scale value corresponding to the blue sub-pixel is a gray-scale value 641. In this way, a data voltage corresponding to the gray-scale value 2734 may be input to the red sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to the gray-scale value 2734 may be input to the green sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to the gray-scale value 2734 may be input to the blue sub-pixel in the first sub-pixel unit SPX-1, a data voltage corresponding to the gray-scale value 641 may be input to the red sub-pixel in the second sub-pixel unit SPX-2, a data voltage corresponding to the gray-scale value 641 may be input to the green sub-pixel in the second sub-pixel unit SPX-2, and a data voltage corresponding to the gray-scale value 641 may be input to the blue sub-pixel in the second sub-pixel unit SPX-2.
For example, with reference to Table 4, with a current original gray-scale value of 127, a first target gray-scale value of 2734 and a second target gray-scale value of 641 as an example, as shown in
